Cozy Roasted Butternut Squash and Sweet Potato Soup Recipe

I love a good soup moment—especially when it’s full of color, flavor, and warmth. This Roasted Butternut Squash and Sweet Potato Soup is exactly that. It’s the kind of meal I pull out when the leaves are turning, my kids are hungry after school, and I want something comforting but also nourishing. With roasted vegetables, fragrant spices, and a smooth, creamy texture (no heavy cream required unless you want it), it becomes a dinner favorite for all skill levels.

Why you’ll fall in love with this Roasted Butternut Squash and Sweet Potato Soup

• It uses everyday ingredients that don’t cost a fortune.
• Roasting the squash and sweet potatoes brings out sweetness and depth of flavor.
• Blender or immersion‑blender friendly—smooth or keep some texture.
• It reheats beautifully, making it ideal for leftovers or meal prep.
• Family‑approved—my kids ask for seconds, and it’s vegan‑friendly if you skip the optional cream.

When I made this last week, I roasted the veggies while I helped my youngest with homework. By the time she finished, the house smelled amazing and dinner was practically done. That, to me, is a win.

How to make this Roasted Butternut Squash and Sweet Potato Soup

Here’s the step‑by‑step. I keep it simple because I know busy families need an easy plan.

1. Roast the vegetables

1. Preheat your oven to 400°F.
2. In a large mixing bowl combine the cubed butternut squash, sweet potatoes, carrot, half onion, and garlic.
3. Add olive oil, salt, and pepper. Toss until everything is coated.
4. Spread the veggies out on a large baking sheet in one layer.
5. Roast for 30–45 minutes, stirring halfway through, until they’re tender and golden brown.

2. Make the soup

1. While the veggies roast (or in the last ~10 minutes of roasting) melt butter in a large Dutch oven or stockpot over medium‑high.
2. Add the diced onion, diced carrot, and celery. Sprinkle in salt and pepper. Cook for 3‑5 minutes until veggies soften.
3. Stir in the ground cinnamon, rosemary, sage, and nutmeg. Let the spices bloom for about a minute.
4. Add the roasted vegetables and pour in the broth.
5. Use an immersion blender (or transfer to a blender) and puree until smooth or keep some texture depending on your preference.
6. Heat through another ~5 minutes. Taste and adjust salt and pepper.

3. Serve and enjoy

Ladle into bowls. Top with a swirl of heavy cream or vegan option, a dollop of sour cream, and sprinkle pumpkin seeds if you like. Serve with crusty bread or a fresh green salad.

Tips & variations for this Roasted Butternut Squash and Sweet Potato Soup

• If you’d rather skip butter, use olive oil for a fully vegan version.
• Add a pinch of smoked paprika or cayenne if you like a little heat.
• Swap in coconut cream for a tropical twist.
• Use sweet potato, butternut squash, and even a parsnip for extra sweetness.
• Make it ahead: the soup thickens overnight—just add a splash of broth when reheating.
• Leftovers? Freeze in airtight containers for up to three months.

Common questions I get

What’s the secret to a smooth texture? Purée thoroughly using an immersion blender and ensure your roasted veggies are tender.
Can I make this gluten‑free? Yes—this recipe is naturally gluten‑free unless you add bread on the side.
How do I keep the soup from being too sweet? The onion, celery, and spices balance the natural sweetness of the squash and sweet potato. Taste and adjust as needed.
Is this healthy? Yes! You’re getting fiber, vitamins, and plant‑based nutrients with minimal processed ingredients.
Can I make it in the slow cooker? Sure! Roast the veggies first, then add everything else to the slow cooker and cook on LOW for about 6 hours.

What to serve with the soup

• Crusty garlic bread or toasted baguette
• Mixed green salad with vinaigrette
• Roasted Brussels sprouts for texture
